Sonic laser has been developed to make a live sound animation with three colors of laser pointers (R, G , B). This work visualises different colors of laser pointer and triggers sound when the program detected each colors; sound and lght are interrelated together to be interacting with each other. Also, the light particle is converted into vector image so audience can watch animated moving colored particle depends on the laser pointer’s color. Devices such as webcamera and project makes feed back loop to make generative system automatically. In this work, flickering light (laser) makes some narrative by moving simple circles and lines with just simple devices and computer vision technology.
